Abstract The search for double Higgs production in b b ¯ W + W − $$ b\overline{b}{W}^{+}{W}^{-} $$ , where both W bosons decay to leptons, has been rehabilitated as a good option to investigate key processes within the Standard Model scalar sector

Neste trabalho consideramos extensões do Modelo Padrão contendo vértices quárticos anômalos parametrizados por operadores efetivos de dimensão oito. Estes alteram o comportamento das amplitudes do tipo VV VV, onde V pode ser o fóton, o bóson

We study the lepton-induced resonant production of color-adjoint leptons (leptogluons) at the LHC employing the lepton parton density function of the proton. We demonstrate that this production mechanism can be useful to extend the LHC ability to sea

Nesse trabalho procuramos por sinais de uma nova física através dos acoplamentos tríplices entre os bósons de gauge, dos acoplamentos do Higgs e dos acoplamentos entre os bósons de gauge e férmions em três análises diferentes. Na primeira, fi

The off-shell Higgs production in pp -> ZZ at LHC provides at present the most direct measurement of the Higgs width in the absence of beyond the standard model contributions. Here, we analyze the impact of anomalous Z couplings to fermions on the Hi

We obtain the partial-wave unitarity constraints on the lowest-dimension effective operators which generate anomalous quartic gauge couplings but leave the triple gauge couplings unaffected. We consider operator expansions with linear and nonlinear r

We study the effect of operators generating dipole couplings of the light quarks to electroweak gauge bosons on several observables at the LHC. We start by demonstrating that the determination of the gauge- boson self-couplings from electroweak dibos

We perform a comprehensive study of the Higgs couplings, gauge-boson couplings to fermions and triple gauge boson vertices. We work in the framework of effective theories including the effects of the dimension-six operators contributing to these obse
